12"x24" sump for sale or trade

Not sure if anyone is in need for this. It has only been used for approx 3 weeks total. It does have scratches on the bottom, but otherwise great condition. I also have a sock (7inches?). Sock is not in great condition since I used it in a different sump that had come with my tankhe sump is an eshopp's brand, I believe it is 17 inches deep and I'm not sure how many gallon's it holds. I am willing to sell it for $75 since it is so new or I would really like to trade for coral or fish. I would really love some LPS coral, but I'm not really picky as I only have about 2 small pieces and 2 frags.
